Abstract (en)

[origin: US2009240094A1] The invention relates to a process for preparing propene from propane, comprising the steps: A) a feed gas stream a comprising propane is provided; B) the feed gas stream a comprising propane and an oxygenous gas stream are fed into a dehydrogenation zone and propane is subjected to a nonoxidative catalytic, autothermal dehydrogenation to propene to obtain a product gas stream b comprising propane, propene, methane, ethane, ethene, C4+ hydrocarbons, carbon monoxide, carbon dioxide, steam and hydrogen, C) the product gas stream b is cooled and steam is removed by condensation to obtain a steam-depleted product gas stream c, D) carbon dioxide is removed by gas scrubbing to obtain a carbon dioxide-depleted product gas stream d, E) the product gas stream d is cooled and a liquid hydrocarbon stream e1 comprising propane, propene, methane, ethane, ethene and C4+ hydrocarbons is removed by condensation to leave a residual gas stream e2 comprising methane, hydrogen and carbon monoxide, F) the liquid hydrocarbon stream e1 is fed into a first distillation zone and separated distillatively into a stream f1 comprising propane, propene and the C4+ hydrocarbons and a stream f2 comprising ethane and ethene, G) the stream f1 is fed into a second distillation zone and separated distillatively into a product stream g1 comprising propene and a stream g2 comprising propane and the C4+ hydrocarbons.
